Several years ago I received a box from a friend who still lives in West Virginia, who is aware, and was aware of my layout, and the area it was based. In the box was a present of a bag of coal, that had been somewhat pulverized. A note said, ” add this to your hoppers”. Well, I did just that! I had to again pulverize the bag to get it down to scale size, but the result is realistic to say the least, not to mention dirty! I can actually say I’m running real West Virginia coal on my layout as shown below. In the second photo, you’ll see however some hoppers have resin coal loads from Motrak, as I discovered during a derailment (yes, I had a derailment near Blue Creek), just how dirty and messy a cleanup of real coal can be! The closeup of the two hoppers under the tipple at Hitop have the real coal.
